controls?

[Homer Pimpson]

I don't like the X key to shout at NPC because i have to take my hands off my movement keys and it's awkward to press for me. does anyone else customize the controls, and if so, what works for you? I also don't like T being the flashlight as I would rather be able to switch it on and off quickly. I will probably bind my mouse to that. what works for you all?
